Going for a run--or a race--almost always meant grabbing the GPS and often also meant setting a target pace and distance. For the last four and a half years, this was measured by a Garmin Forerunner 201. That's the large rectangular model in the original "brick" form factor. I've come to love the device. Training is great because the distance log, as well as the pacing, keeps you honest. Racing is probably better because it helps a lot with the pacing (but then I also had PRs in race where I had forgotten the GPS at home). But there is a downside. This model sometimes takes forever to find tracking, and has interference / weak signal problems when it is cloudy or moist. But worst of all, it just bonks out in the 'urban jungle' downtown where it drops signals too easily. And now after all these years the display had some minor damage, the strap didn't really hold anymore, and it was generally time for something new. On Tuesday it even lost a quarter mile when we were going for a short but really fast three miler. But then a few days prior I had followed fellow Debian marathoner Christian and used my birthday at the end of this month (as well as the upcoming Boston Marathon) as an excuse for conspicuous comsumption. After some price comparison, I ordered a factory reconditioned Garmin Forerunner 405 from this web discounter at a nice rebate to the regular price. It arrived this afternoon, seemingly shining new and I have been fiddling with it for the last little while. This device features wireless data transfer to a usbstick. This meant booting the laptop in windoze for the first time in years to load the 'client software' after which data transfer proceeded. The Garmin Connect site has very slick presentation and aggregation of the data. The trouble is of course how to get the data there when running Linux... Christian had mentioned the garmin-forerunner-tools package. Unfortunately, this seems to really be written for the Forerunner 305 models as it doesn't see the device at all. Some more googling lead to this page and the gant tarball. All still fairly raw, but with some prodding in the settings of the 405 ('pairing' set to 'on', 'force send' set to 'yes'; which may have to be reset each time ?) I got my two xml files off the gps watch. Yay. We'll see what mode I will settle one. With the 201 and its ancient serial port, I basically just dropped the run and training histories which their fairly limited data collections. Last but not least, fellow Oak Park runner Peter Sagal had a humorous Runner's World column on the whole GPS geekyness. If he'd only known how to pair it with programming geekyness...

While I did not think I would continue hacking on VoiDroid after achieving a semi-broken proof-of-concept implementation, it seems that I can t get out of it easily :-). I spent today trying to implement a solution which would allow the native C++ code to call into Java - for example, if we have a call in progress, and want to update the call status displayed to the user when it changes. The JNI library has some native callbacks which are getting called on call state changes, but getting the information to Java turned out to be a quite an experience, which, I thought, would be amusing to document, and, hopefully, save someone some quality bang-head-on-desk time. 1. Some of the threads calling native callbacks were initiated in Java (and thus known to JVM), and some where not, they were started in the native code. As JVM did not know anything about them, JNI calls would fail without too much explanation. Eventually I figured that out, and started attaching them as appropriate (JNI provides facilities for that). 2. Even after attaching, I could not resolve references to my classes from the native code, until I found a mysterious line in JNI docs: When a thread is attached to the VM, the context class loader is the bootstrap loader.. Basically, it means that when you attach a native thread, it is only capable of resolving built-in Java classes. 3. I later found a reference to a technique, suggesting to cache a good classloader from a Java-initiated thread, and later set the classloader for the attached thread to it. I implemented that, only to find out that Android s JVM is not your regular JVM, so things are slightly different here, and this technique does not work. 4. Luckily, there is an incredibly useful post describing the problem, and suggesting a workaround: caching an instance of needed class globally in native code, after calling NewGlobalRef on it, to avoid garbage collection on exit from a native function. I did that, however I only had access to the class, and Android JNI only supports calling NewGlobalRef on an object, so I had to create a dummy object in the native code (JNI_OnLoad() function, actually) and cache that. 5. That finally enabled me to call into Java from native, attached threads (w00t!). Unfortunately, you are not allowed to modify the UI (exactly what I wanted to do from my Java callback!) from a non-UI thread, which brought me right back to the drawing board. 6. As callbacks initiated from native code would not work for this reason, it was suggested to me to use a classic producer-consumer mechanism, getting Java call into the native library block until new information gets delivered by a native thread. Easily done with some pthread mutexes, and the goal is close, right? 7. Wrong! Now the problem was that if I started a UI Java thread, which would call the native function in a loop to retrieve the data (it would not actually spin, as the native function blocks until new data is available), then it would be declared not responding by the UI framework in a few seconds. I could start a non-UI thread for that, but you guessed it a non-UI thread is not allowed to update UI! Instead of resolving the problem we just shifted it into the Java land. 8. While I was simply thinking about stuffing the result into a class variable and passing it to the UI thread this way, this tutorial, showing how to display a progress indicator while doing some heavy calculations in the background, provided a more elegant idea. One can use Android s android.os.Handler class to pass messages (with arbitrary payload) between threads. That was the last piece of the puzzle, which allowed me to finally achieve a working implementation (some 10 hours or so later :-).

This is a really slim and really incomplete description of the events turning really bad for Romania and severely bad for Moldavian civilians.

• Moldavia calls his ambassador from Romania
• the peaceful protests turn violent on Tuesday (while Voronion recognised for Ria Novostni that they allowed the protesters to control for a day the Presidential building and the Parliament (in Romanian)
• the Moldavian public is kept in the dark by the authorities: the national radio-television doesn't cover the events, the independent media is not allowed to report the events
• in the rural areas of Moldavia no other media is accessible except the national television which is controlled by the Communists
• Moldavian police men tear down a wall close by the Moldavian Parliament during the violent turn of the protest
  
• Moldavia accuses Romania without any proof of implication in the events in Moldavia
  
• The Romanian ambassador Filip Teodorescu, and the Counseling Minister of the Romanian Embassy in Moldova, Gabriel Gaboran, are declared persona non grata in Moldavia; Romania can't do the same since the Moldavian ambassador is not in the country
• Vladimir Voronin announces visas will be introduced for Romanians (an abussive measure since the EU should have been announced of such a measure with 48 hours in advance)
  
• Romanian authorities respond by:
• a ferm denial of the unproven accusations - from what I have seen CNN and Euronews simply don't accurately represent the declaration, and the texts put under quotes - the word "provocation" - imply that the Romanian position is not honest
  
• they declared that they will NOT declare the Moldavian ambassador as a persona non grata and that the regime of gratuitous visas for the Moldavian citizens will not change
• EU DOES NOT ANSWER AT ALL TO THIS ABUSE AGAINST EU CITIZENS
  
• Wednesday protests are quiet but media access is highly restricted and inaccurate information is aired through the national Moldavian Television
• Romanian journalists from Antena 3 were harassed, followed and, fearing for their safety, they appealed OSCE authorities in Moldavia to be able to leave the country safely
  
• Wednesday and Thursday many arrests occur in Moldavia and the Romanian officials requested the Moldavian officials to tell them if among the arrested people are any Romanian citizens; no answer was provided by the Moldavian authorities
• France, Sweden and Czehia and some other EU members declare that they "understand the complexity of the relation sensible issue between Romania and Moldavia" and appeal to Moldavia to rebound the diplomatic relation with Romania - WHAT? In Diplomatic lingo that seems to mean something like "we know Romanians are idiots, but please, Moldavian authorities, let's get back to dialogue"
  
• Today, Friday 10, the Moldavians are called to protests and the authorities are authorized to use real ammunition
• Teachers, university administration personnel, opposition representatives announce that people should not attend the protests and measures will be taken against anyone allowing people (mostly youngsters) to attend the protests
• Russia declares that "the EU has a member state that hasn't clearly delimited its borders" which obviously refers to Romania, thus attacking Romania and alleging that Romania has unionist expansions; EU DOESN'T DO ANYTHING!

Are we living in a parallel world? What interests would Romania have to ever consider that it would be involved in this? Moldavia is the poorest country in Europe, has huge problems with justice, corruption, criminal activity, social security, border security (Transdnistria) and other issues which Romania does NOT want to import since we're already in a bad position by ourselves!


WHAT THE HELL IS EU DOING? Romania is a member of the EU and it seems all the attacks against Romania are not addressed in any way by the EU, on the contrary, EU members either assist passively, look the other way or even allow us to understand that indeed they think Romania is involved.

Many people in the western world are completely unaware that in the Moldavian Republic there is an ongoing protest against the current Communist Party which is at power after the parliamentary elections held on Sunday. The protestants accuse the Communists of election fraud and there are numerous reports of dead people being recorded as voters, people which, by religion, chose not to vote, and other several people which couldn't have voted.

Tuesday the protests took a violent turn, apparently "aided" by some instigators which were reported to be seen as recording the protesters, taking notes and, generally, not fitting the picture. During the day the national television broadcasted absolutely no information on the events, and aired documentaries, cartoons and no news on any of the protests. To me, this looked very much alike what the Romanian Television aired during the Romanian Revolution in December '89 when during the fights in the streets of Bucharest the Television aired no images from the centre of Bucharest.

But, back to Moldavia, at the end of the day, sadly, the Parliament and Presidency buildings were devastated, making it easy for the Communist leaders to produce some disinformation propaganda based on real footage.

Yet again, sadly, but it seems under the protection of some of the aforementioned instigators, the flags of the EU and Romania were waved at the highest levels of the Parliament building during the time the protesters allegedly took over that building (there were several reports that the Police forces actually simply let them in, without actually needing/being forced to do that; also the passivity of the policemen seen in the footage from Romanian televisons was obvious).

As many Moldavian students live and study in Romania, some of them wanted to go home and take part at the protests happening in Chi in u. To their surprise, many of them were denied the right to enter their home country. Many, if not all, Romanian journalists were also denied access in the country accusing alternatively technical issues, lack of proper papers (although only the passport or the ID card was officially required), lack of safety, or simply refusing without reason.


Today, the Moldavian president Voronin, accused Romania as being behind the manifestations in Chi in u, Moldova's capital and said it will declare as a persona non grata the Ambasador of Romania in Moldova, and thus forcing him to leave Moldova within 24 hours. He went even further and said that visas will be required from now on for Romanian nationals. As soon as this was announced, it was one of the most invoked reasons by the Moldavian customs as a rejection reason, although, according to Moldavian Embassy officials in Romania, no rules or procedure were known for the release of visas for Romanian nationals.

Also, during Wenesday, Moldavian crossing points were opened and closed alternatively but incosistently accros the entire border for Moldavian nationals. Romanian nationals were denied in most cases (although some Romanian truck drivers were reported as allowed to cross). At some point during the day the Moldavian officials from the customs told the Moldavian students awating at the border that they are offered access on the condition they go direclty home with the buses provided by the Moldavian customs and were warned that going to Chi in u wasn't a smart choice for them. Some of the information from students which managed to enter their home country suggested that is advisable to not enter the country since they were going to be denied of the right to leave the country later, when they were to return to Romania to their studies (after Easter).

What's sadder is that the Moldavian voting system is built in such a way that the vote counting, in the end is done by Government officials behind closed doors, inside a Ministry. OTOH, the international official observed the things which happend in public, but did not see any of the dead voter lists (since they were not present when those votes were casted), and declared the vote as mostly legal and without major or significant incidents.


According to the media, before the elections, the Communists were credited with 35-37% of the votes in an independent poll, while in the exit poll conducted by the Communists themselves they were credited with 42-45% of the votes. In the end the last official partial results credited them with approximately 51% of the votes.

About Vladimir Voronin, it is a known fact that he has double citizenship, Moldavian and Russian and is a reserve general within the Russian Army and currently has a pretty nice pension from the Russian state.


All I can say is that, although the Moldavians' desire to have a real democracy is a legal and reasonable request, the western world chose, due to the international circumstances, to look the other way around and not to incommodate Russia in any way. Moreover, to accuse Romania to have unionist desires an act upon those desires is planly stupid since now Romania is part of the EU and Moldova uniting with Romania is simply impossible now, since Moldavia's economy would sunk even more the fragile and regressing Romanian economy and Romania would instantly fail the EU requirements which would mean disaster for us.

I just wanted to make an USB stick bootable and wondered why mkdiskimage -4 /dev/sda 0 32 64 complained about the disk having too many cylinders. After a few moments, it ocurred to me that since libata, the system hard disk has become sda and that the stick was sdb or sdc. One ctrl-C later, fdisk confirmed both counts: That I accidentally started mkdiskimaging my main system hard disk and that the partition table was already gone. A few hours later, the notebook is back in business without too much data loss. Lucky me. My notebook has an alibi installation of Windows XP in its first primary partition sized 4 GB. Since I aborted the mkdiskimage process early enough, I hoped that only the windows installation was hosed. The Linux system is entirely in LVM (with crypted LVs), and LVM hadn t noticed yet that its PV was gone. I reckoned that I still had a chance to rescue my data if I didn t reboot. So I hastily commandeered an USB hard disk (thanks, $CUSTOMER, for quickly supplying one), fdisked, pvcreated and vgextended it and started the pvmove. While this was happening, I theoretically was able to continue working, which I didn t because I was afraid of losing. About half an hour into the copy process, the USB disk chose to deregister itself and the pvmove aborted. Rebooting the disk made it reappear as sde (it was sdd before), and miraculously, a new pvmove call just worked. However, a good fraction of actions on the shell resulted in a lot of input/output errors on the screen. I guessed that this was the first sign of my data finally dying, but I let the pvmove continue. After the pvmove was finished (which was rather fast since the move of the crypted LV means that the crypted data is moved and not de- and recrypted), I had to recreate a /dev/sda2 partition with type 8e before the LVM tools allowed me to vgreduce the VG. I then zeroed out the first 10 GB of the internal disk and spent a few hours reinstalling and patching XP from scratch before I finally went through the pvcreate, vgextend, pvmove routine in the other direction. Then the big moment arrived: fsck of all LVs. I guess that the reason for the input/output errors was that /usr was completely hosed (no single file outside lost+found), but /home and all other file systems holding data where the way back to the (a week old) backup would have been quite painful were ok. I pulled /, /usr and /var from the backup to be consistent again, updated to current sid (avoiding KDE 4 for the time being) and could start working again. The only real loss was a few hours of work that were stored in /usr/local which died along with /usr, so the result of my stupidity was not very catastrophic but still a good lesson. And I have learned that LVM is a robust and resilient beast. Good work. Now I d like to know what happened to my /usr - I always had the impression that pvmove should not break data even when the target disk suddenly goes away...

I live in a 55 year old house. That's not something to be worried about, of course, but it does mean that my house needs major maintenance works to continue to be in good shape. This week, said major maintenance jobs began. We are in the process of replacing all of the windows - It might sound a bit scary by today standards... But if you have ever been here... Well, this house was built in a very different era, when the newly built University City lied several kilometers South of the city border and land was cheap here. Most houses in the area were built for University teachers (this particular house was for twenty years home to Marcos Moshinsky, Mexico's most important Physicist who, coincidentially, passed away last week; Dr. Moshinsky was my father's teacher and mentor). Anyway, we just started the window teardown process. The workers are going quite faster than I expected. Still, I am worried about the waitfor(). As anybody who has come to this house will know, we live on a very busy avenue. Even 30 years ago, when my parents moved here, they installed double glasses on every window - But did some mistakes (i.e. we have some broken glasses which are unchangeable for practical purposes). This time we decided to buy from an established vendor for this kind of windows. Double-glass windows are common in colder regions - But here, they are quite rare. Strange, being this a noisy city... So we researched a bit, and found a vendor with good quality - Multivi, in Puebla. What we didn't count on... Is that they were so informal. We paid in late December and were told delivery would take around two months... And we are still waiting, this time pressing them for a commitment. After all, we are already lacking several windows, and... Well, around May we start having rains. We DEFINITIVELY don't want to be stuck without windows by May! Anyway... I recently sent out a semi-VAC anouncement to debian-private. And this is extensive to any project I am related to: The next days I will be paying more attention to whatever needs to be done at home. Please don't expect prompt replies to mail from me (yes, as if I usually replied promptly...) I do have network access, but not much computer time.

A few hours ago, a new version of kernel-package was uploaded to experimental. This is a major change,and I would appreciate it if folks took it out for a spin, kicked the tires, and provide feedback about where this version is lacking. This is only part of the way along in this development cycle. I would like to add a debug-info separation, either in a different directory than / in the image packages, or a separate package by itself. I would also like to create an overlay directory for /usr/share/kernel-package/, so people can inject code or override the defaults for kernel-package easily. I am also willing to make any changes to standardize the handling of hook scripts for kernel packages in Debian.

This blog post is mostly a test to see the engine is still working :-) But I don t think it hurts to mention that the deadline for registration and for submitting talks and workshops is in 8 days, so hurry up, if you haven t already! Of course you can also register later, but then you won t get sponsored and maybe won t get a timeslot for your proposal. That s all for now, stay tuned for more!

I ve been tilting at windmills, recently. Windmill, actually. It s a Python program that lets your computer drive a web browser, without any human interference. We use it at Akoha to run tests that make sure that our website works with Firefox. We use it to help us test our site with Internet Explorer. So I dutifully set up a Windows machine and tried to get it to run our test suite. I quickly realized that our software was going to need something more Unix-like. Cygwin is the answer to that problem. It provides a full POSIX environment inside Windows. I built all our software and tried to fire up Windmill.

ImportError: No module named _winreg

Uh oh! Windmill needs to access the Windows Registry. According to the winreg documentation, it s only available for Windows. Apparently, Cygwin doesn t count as Windows. So I spent the weekend writing a library that fills in the gap. cygwinreg allows you to read, write, and explore the Windows Registry from inside Cygwin. Whenever you want to use winreg, use cygwinreg instead.

import sys
if sys.platform == "win32":
    try:
        import winreg
    except ImportError:
        import _winreg as winreg
elif sys.platform == "cygwin":
    import cygwinreg

After I did that, I plugged it in, stepped back and ran my tests. They worked!

Download cygwinreg
or install it with
easy_install cygwinreg

Yay! one more big step towards being a universal operating system. Please welcome kfreebsd-i386 and kfreebsd-amd64 versions of GNU/kFreeBSD to be among the list of official architectures in Debian.

The GNU/kFreeBSD installer is based on FreeBSD sysinstall and is not the regular debian-installer, but efforts are underway to build a native Debian installer.

Here is the Australian Electoral Commission documentation on how to register a political party [1]. It includes the requirement for A Microsoft compatible electronic membership list (and paper copy) providing the following information . So a prerequisite for registering a political party appears to be the ownership of a PC running Windows. While it may be the case that I could create a plain text file on a Linux machine and append some CR characters to each line, or create a CSV format spread-sheet/database file the most common interpretation of this is likely to be that MS-Office is required. Such blatant promotion of a software vendor in a government document is unacceptable. Anyone who wishes to use other software for their political activities should be permitted to do so without restriction.

Here I am, utterly disgusted. Last Thursday, around 11pm, two dozens of members of Assembl e Nationale (one of the two parliament chambers in France) voted the infamous law nicknamed HADOPI. Great... For the record, this chamber in principle counts 577 members. This law is an awful blow to the Internet, the freedom of expression and the legal system in France. The official aim of this law is to put a stop to illegal file-sharing within France. With this law, specially appointed private companies will file accusations saying: this IP downloaded something illegal at this date to a central authority, and this authority will send two warnings before cutting the Internet connection of the alleged illegal downloader for up to a year. You will notice that there is no mention of what the incriminated person allegedly downloaded. There will be no possibility of appeal until the sanction is executed. This scares the hell out of me. This spits upon so many aspects of the French legal system that it is honestly impressive... What about the French principle that says that everyone is innocent until proven guilty ? Here, you are declared guilty based on a rather weak evidence (on IP address !), and you'll have to prove your innocence. What about the principle that there needs to be a fair trial before the execution of the sanction ? You'll have to prove you are innocent after the execution, with the additional fun that it will turn almost impossible to prove it. Not to mention the fact that the companies harvesting IP addresses of alleged offenders will have a great deal of access to data you're exchanging; what about privacy ? For the record, this privilege, violating the way justice works in France, had only ever be granted to anti-terrorist cells. The fun thing is that this law is useless, at least in terms of the its official goal: the day it comes into application, illegal file sharers will encrypt their exchanges or fake their IP addresses, or do whatever else they might want to do to guarantee their anonymity, and no company will ever be able to find out what it is they exchange. I won't even mention the number of false positive of these automatic accusations: many innocent French web surfers will have their connection cut without ever knowing why and without any possibility to fight back. So, what is the real goal ? Or what will be the use ? I can only speculate, of course, but it is tempting to think that this law could be used to regulate what is being expressed from France on the web. Someone is saying disturbing things ? Well, easy to shut him/her up: either fake downloads from his/her IP address or bribe a company into filing false accusations, and you'll effectively remove his/her connection while having the opportunity to further discredit the person by publicly disclosing that he/she is such a pirate that their connection was cut... Sounds neat, doesn't it ? In my childhood, teachers kept on saying that France is the country of human rights, but I can't help thinking this is less and less the case[1]. Well. That was a long rant. But I can't keep it inside: this is touching me too much. I'll add that I'm not downloading anything, and I don't have anything a priori against laws which would tend to regulate illegal file sharing. I just don't think that the (small) profits of a few justify spitting upon the freedom and the elementary rights of all people living in France. Further information, in French, can be found there. The full text of the project can be found on the website of Assembl e Nationale. [1] Please don't get me wrong. There are many countries where life is definitely more difficult than here, and where human rights are constantly scorned upon, which is fortunately not the case here yet.

Long time since my last movies posting ... Just discovered the U.S. TV series Supernatural, in an episode showing the two heroes being introduced for the first time to the writer of the book series Supernatural , which contains the life of the two heroes. (Strangely, it showed up when I searched for Tarantino's Reservoir Dogs on a torrent search engine.) I'm not quite sure what to think about the series, judging from that episode. I read a lot of fantasy and I like the real-world / fantasy world crossover every now and then, but Supernatural is quite cheaply made. Watching this one episode was fun, but I have no idea if I would actually watch it regularly. (I find, generally, that fantasy is difficult in movies. Lord of the Rings is very well executed and mostly presents the world as just a normal world , and I'm forever thankful to Jackson that he shares my opinion I think he says as much in the bonus materials on one of the DVDs that magic with smoke and flashes mostly ends up in major silliness. I have neither read nor watched anything of the Harry Potter epic, so I can't comment on that.) While I can't comment on Reservoir Dogs yet, I finally got around to watch From Dusk Till Dawn by director Robert Rodriguez, and with Tarantino (also co-writer of the movide, and if you watch the making of, co-director even if it's not in the titles) and Clooney as two of the main characters, together with a wonderful Juliette Lewis. That's certainly one of the movies I'll watch again, several times. Great soundtrack, too. Yesterday, I was a bit disappointed after I watched Time Bandits; Gilliam's later films got much better. It takes something to make a stop motion movie in today's time of cheap and easy computer animation ... so I really liked Tim Burton's Corpse Bride, if not for the rather straightforward story, but for the look and the atmosphere. The movie is also more a musical than a film, which I like very much as well.

It's been a long long time since I last posted anything at all, so this is a post to warn of impending doom. I've switched from a static html website (well, it was statically generated when I edited source files I then ran a bash script that fired off a perl script several times...) to a fully dynamic, django 1.0 backed website - this might mean that I manage to update things more often! I've also taken the opportunity to convert the previous content in to ReST, so it's actually easier to edit too. There's still work to do - but it's now "good enough" to be used, and I'll split the code out in to better chunks later on. So, anyways - that's what I've done with my day - so I expect all the aggregators to now break on the new feeds...

I don't use Emacs myself, and I don't recall a single Emacs user complaining about accidentally triggering Ctrl-Alt-Backspace on their way to M-C-E-A-S paste-output-of-doctor-into-irc. Most of the grumbling came from actual users (i.e. people who don't know what an X server is, let alone how to configure it, let alone to email xorg-devel@ about it), rather than people who are perfectly capable of changing the default[0].

Regardless, Peter came up with a perfectly sane plan which makes it very easy indeed to optimise for clients with stuck grabs (being that termination requires you to be processing input events in the first place, in which case you're likely doing reasonably well anyway).

[0]: Yes, the text is woeful. Sorry.

With our AGM in Plymouth rescheduled until June or July, the Cooperatives-SW board will meet in Bristol on Monday. Cooperatives-SW aims to represent co-operative and mutual enterprises in the region. As with previous meetings, if you d like to meet up beforehand, let me know through this blog, identi.ca or email. Bristol is near HQ, so I expect I ve met most people there who want to talk to me. The meeting is just before a co-operative and mutual housing hearing. Places will be limited so please contact CDA (Brave Ltd) on 0117 989 2536 if you would like to reserve one.

Guadalinex-EDU: New educational distribution based in Jaunty

Guadalinex Edu is a new GNU / Linux distribution developed by the Advanced Center for ICT Schools Management (CGA), initially created for use by the educational community of Andalucia, Spain which will be available for teachers and students within the domestic sphere. Guadalinex Edu distribution is equivalent to the future Guadalinex V6 citizen but oriented to the educational sector.

Looking for the highest possible level of stability in the distribution, the CGA will be releasing a beta version of the distribution, installable by anyone who wants it. The aim is to involve the educational community in the stabilization and development of Guadalinex Edu, before its deployment in local schools.

Guadalinex Edu Beta 1 is fully functional, but should not forget that this is a beta version which may contain errors from both: the applications included by the CGA in the distribution, and errors coming from the base distribution where it must be installed (Jaunty Jackalope Ubuntu 9.04), so it is not recommended for use in production computers and, in any case, it is recommend making a backup of important data before installation.

Within an ICT Center, Guadalinex Edu will take advantage of the network infrastructure and servers from the center to offer:

• a system that allows any member of the center to become remote user of its data in any computer regardless of the dependence location in the center.

• a system for transmitting multimedia content among computers in a classroom

• a system of interaction between students and teachers via the computer

For domestic users, Guadalinex Edu is offered as a meta package to be installed on Ubuntu Jaunty and offers tons of applications like:

• Celestia (space simulator)

• Kstars (Planetarium)

• Kgeography (Maps)

• Parley (Vocabulary)

• Squeak

• DRAE Spanish Search tool (Lemurae)

• GNU Octave

• Kbruch (fractions)

• Kig

• KmPlot

• KSeg (Geometry)

• Mathwar (Game of calculus)

• QtOctave (numerical calculus)

• Freemind

• Blender

• Audacity

• Festival GUI

• KTouch (Typing)

• Kompozer

• Umbrello

• K3b

• Kino

Plus all the benefits of Guadalinex:

• Spanish translation of many applications

• Support for electronic ID Card

And Ubuntu:

• A wide range of media devices support (kernel 2.6.28)

• Firefox 3

• OpenOffice 3

• XOrg 1.6 , etc

Installation instructions for home users are available here(In spanish)

Original link in spanish here

It's quite interesting. Twitter has this snippet in its registration page: By clicking on 'Create my account' above, you confirm that you are over 13 years of age and accept the Terms of Service. At least currently when you click it leads you to a page that says: Something is technically wrong. I'm very happy to accept that, but I have this strange feeling that it's not what they intended to have there...

Well, I normally despise of thinks like this link collection, but I thought I might add it anyway, since these are useful links for me and if I don t post them here, I m likely to forget where to find them in the near future:

1. Sean Finney has a nice post about storing the list of parameters a (shell) script got in a way that it can be restored later. Quite handy if your script walks through the arguments parsing them (and consuming them while doing so) but you want to be able to display them in a helpful way if the parsing fails at some point.
2. A while ago, Ingo J rgensmann had a post that helps retrieving files from lost+found after a filesystem check, provided that you run his helper script on a regular basis. The same approach can also be used if you have a backup of all files, but lost the sorting work you did after the backup was done. This is possible because running the script can be done more often then you would normally do backups.
3. He also has a small post about mtr oddities when IPv6 comes into play
4. Adeodato Sim wrote about databases and when timestamps that store the timezone information really are more useful then timestamps that don t.
5. Adeodato also has a short post on using ssh as a socks proxy, which can be quite handy if you are behind a firewall.

Update: Fixed link to Ingo s file retrieval from lost+found article. Thanks to Patrick Schoenfeld who pointed me at the wrong link.
Also thanks to the anonymous poster who found an alternative way to store and (in a way) restore commandline parameters. The solution doesn t work in an as general way as that by Sean Finney et al., but it is much shorter and therefore interesting for where it can be used (when you control how commandline parameters are processed). See comments on this post for details.
